Today we’re hosting more than 300 CIOs and IT professionals from around the world in Paris at Google Atmosphere, our annual European event dedicated to cloud computing—web-based applications that are built on shared infrastructure and delivered through the browser. This year, the discussion at Atmosphere is focused on how companies can benefit from the breakthroughs in productivity and security that cloud-based applications are uniquely capable of delivering.

This event also marks some major milestones:

As of today, more than 3 million businesses have gone Google, and over 30 million users within businesses, schools and organizations now depend on our messaging and collaboration tools.

We’re launching new cloud-powered capabilities: two-step verification to help enhance security and soon, mobile editing in Google Docs on Android and the iPad™.

First, Google Apps Premier, Education and Government Edition administrators can now have users sign in with the combination of their password (something they know) and a one-time verification code provided by a mobile phone (something they have). Users can continue to access Google Apps from Internet-connected devices, but with stronger protections to help fend off risks like phishing scams and password reuse. For the first time, we’re making this technology accessible to organizations large and small without the costs and complexities that have historically limited two-step verification to large enterprises with deep pockets. Furthermore, in the coming months, Standard Edition and hundreds of millions of individual Google users will be able to enjoy this feature as well.

Second, today we demonstrated new mobile editing capabilities for Google Docs on the Android platform and the iPad. In the next few weeks, co-workers around the world will soon be able to co-edit files simultaneously from an even wider array of devices.

Only cloud computing is able to deliver the whole package of productivity-enhancing collaboration, superior reliability and virtually unlimited scale at a price that’s affordable for any size organization. Our Atmosphere event is a nice opportunity to step back and fully appreciate the power of the cloud with customers and future customers alike.
